2 Claims; (01. se -so 'My invention relates to chains adapted primarilyfor use in the jewelry art for bracelets, girdles, necklaces, anklets,arm bands and the like.

The essential objects of my invention are adaptability to the display ofany desired surface ornamentation by engraving, stones, or otherornaments; to insure lightness of weight combined with adequatestrength; to enable the use of a soft metal in construction; to permit ameasure of transverse or lateral flexibility together with longitudinalflexibility to insure such strength of connection of the units as toprevent breaking or loss of the latter; and to attain these ends in astructure inexpensive to manufacture, and wherein units maybe easilyremoved or substituted.

With the above and other objects and advana tageous features in view,the invention consists of the arrangement of parts and details ofconstruction more fully disclosed in the detailed description following,in conjunction with the accompanying drawings more specifically definedin the claims appended thereto.

In the accompanying drawing forming a part of this specification,

Figures 1 and 2 area plan and side elevation respectively of a series ofmy novel units assembled into a chain embodying my invention,

'Figure 3, a longitudinal section of the same taken on line 33 of Figure1, 1

Figure 4, a perspective view of a link prior to closing down the tongue,I

Figure 5, a side elevation of two links partially interengaged, and

Figure 6, a central longitudinal vertical section of the same.

Similar reference characters indicate similar parts throughout theviews. 7

The chain 1 comprises a plurality ofnovel units 8 adapted for facileinterengagement. Each unit is composed of a relatively soft metalincluding tin or the like as one ingredient such as Britannia metal,which imparts a greater degree of pliability and less hardness thanbrass. For this reason the bending operation involved in theconstruction of the link is facilitated and the metal is more adaptedfor the formation therein of seats for stones or other desiredornaments.

The units are individually formed in one piecerear ends outwardlyinclined plane faces con- 1 stituting diverging end abutments l2. Thepoints ID are laterally curved. Integral with the concave or inner sidesof the segments, intermediate their lengths, and oppositely disposedwith relaf the abutments ii, the diameter of the former being less thanthe area of the latter. Transversely disposed rearwardly inclinedspacing bars 9 integral with each unit extend from the lower portions ofthe rear shoulders [2 to a longitudinally disposed tongue 2c of flatstock comprising a vertically disposed rear portion 2|, and a forwardlydirected portion 22 laterally tapering at its free end to a point 23.The under surface of the portion 22 is provided with a longitudinallydisposed convex: shoulder 26. The inner ends of the pivotbars H) arefixed to or integral with the opposite sides of the tongue portion 2iatthe lower end of the latter.

In the initial step of assembling a plurality of units into a chain theportions 22 of the tongues are originally in horizontal or elevatedposition, as shown in Figures and 6. To interengage the units the crossbar N3 of the rear unit is inserted under the tongue of the forward unitand is drawn rearwardly until said bar abuts against the portion 2| ofthe tongue, and the bars !9 of the forward unit loosely register in'thegrooves l5 of the rear unit.

The next step is to manually depress the forward portion of the tongue20 of the forward unit until the point portion 23 thereof reaches aposition between the knobs or projections l3 where which permits aslight vertical movement of the bar 18 therein whereby the chain has acapacity for flexibility in a vertical direction.

The chain has some flexibility also transversely in a horizontal planesince the abutments ll of the body segments 9 are spaced somewhat fromthe sides of the tongue portion 2|, as at 29, and the curved outer facesof the point portions of the segments are slidable against the abutmentsl2, and the recess 21 affords sufiicient space to allow the bars l9 toride out of the grooves I 5 when the engaging unit is transverselytilted.

I claim:-

1. An ornamental chain comprising a plurality of units of relativelysoft metal, each unit consisting of horizontally convexo-concave bodysegments provided upon their forward ends with points and with abutmentsand at their rear ends with abutments, a cross bar connecting the for-,ward abutments, a longitudinally disposed tongue between the segmentsadapted to receive the cross bar of an adjacent unit comprising anupwardly directed rear portion and a downwardly inclined forwardportion, spacing bars connecting the rear abutments to the lower end ofthe rear portion of the tongue to loosely receive the points of anadjacent unit therebetween, and projections upon the segments fixed tothe forward portion of the tongue. 7

2 An ornamental chain comprising a plurality of units of relatively softpliable metal, each unit consisting of vertically arched horizontallyconvexo-concave segments having top and bottom faces and provided upontheir forward portions with lateral abutments and upon their lower facesadjacent the abutments with transversely inclined grooves, and providedat their rear ends with abutments, a cross bar connecting the forwardabutments, a tongue adapted to receive the cross bar of an adjacent unitcomprising an upwardlydirected rear portion and a downwardly inclinedforward portion, rearwardly inclined spacing bars connecting the rearabutments to the lower end of the rear portion of the tongue to looselyreceive the forward extremities of the segments of an adjacent unittherebetween, the spacing bars being adapted to loosely register in thegrooves of the adjacent segment.
